The birthday of Prophet Mohammad (PBUH) is celebrated on the 12th day of Rabi Al Awwal. In Arabic, the holiday is referred to as Eid Al Mawlid an Nabawi. Muhammad united Arabia into a single Muslim polity and ensured that his teachings, practices, and the Quran formed the basis of Islamic religious belief.
Prophet Muhammad (PBUH) was born on 12 Rabiulawal in 570 AD. His birthday is celebrated with religious lectures and recitals of verses from the Koran.
The basic earliest accounts for the observance of Mawlid can be found in 8th century Mecca when the house in which Prophet Muhammad (PBUH) was born was transformed into a place of prayer.
